Abstract
The dynamics of a random ferromagnet with infinite-range exchange interactions and Gaussian distribution is studied. The Green function for the propagation of magnetic excitations is obtained in an exponential form which permits the use of techniques associated with problems involving random matrices. The magnetic properties of this system are obtained and compared with the ordered case.Keywords
